28 Client and Server architecture
The Meter consists of one COSEM Logical Device (LD name: 0-0:42.0.0.255, SAP: 001), which
supports a
• Public Client (SAP: 016)
• Pre-established Client (SAP: 102)
• Management Client (SAP: 001)
• Reading Client (SAP: 002)
The Public client is provided for reading meter’s general information (e.g. logical device
name). Because of lowest access level security (no security) in this type of association, this
client is permitted to reveal some limited information of meter, and is not allowed to read
metering data and performing any programming or changing in meters settings.
The Pre-established client is intended to perform broadcasting and multicasting services
(unconfirmed) services. This type of association includes only the message exchange (not
establishing and releasing). The Pre-established can be considered as an association that
has been established previously. The Pre-established association can’t be released.
The Management client is allowed to perform any operation on devices in point to point
connections. Both services like “Confirmed” and “Unconfirmed” service can be used.
Reading client is for parameters and energy data reading mostly in local access.
